Company patents
Iris Ohyama Inc.
Iris Ohyama Inc. exhibits a surprising patent strategy, with a significant 10.5% of its portfolio in Pumps (Centrifugal) and an 8.8% share in HVAC & Air Conditioning, areas not typically associated with a consumer goods company. While patenting in both these categories saw a 50.0% decline in 2025, the complete cessation of new patents in HVAC & Air Conditioning so far in 2026 (-100.0% YoY) suggests a notable shift away from this sector, contrasting with its more modest 3.5% presence in Domestic Cleaning Devices, which also saw a 100.0% decline in 2025.
